Abstract

coupling arrangement for connecting a light guide (7) which at its one end (6) with a coupling end face (9), to an optoelectronic element (5) in the in one the end (6) of the light guide (7) and the optoelectronic Element (5) receiving coupling housing (1) between the end of the Optical fiber and the optoelectronic element one of an optical permeable Material existing coupling element (12) is arranged, which is in physical contact with the coupling end face (9) of the light guide (7) and that at its the optoelectronic Element (5) side facing a back reflections reducing surface area (16), characterized in that the coupling element (12) lenticular and as an integral part of the coupling housing (1) is formed, and that the coupling element (12) at its the optoelectronic Element (5) facing side has a beveled section.

Description

  • The The present invention is in the field of joining optical fibers with optoelectronic components and is in the structural design apply an arrangement in which a coupling housing a with a coupling end face provided end of a light guide and an optoelectronic element receiving, between the end of the light guide and the optoelectronic Element for reducing back reflections Coupling element arranged from an optically transparent material is.
  • in the Meaning of the invention is intended to be under an optoelectronic element a transmitter or a receiver be understood. An optoelectronic transmitter designed as a transmitter Element converts the electrical signals when electrically driven in optical signals, which are emitted in the form of light signals. One as a receiver formed optoelectronic element converts when charged with optical signals this in the corresponding electrical output side tappable signals. Furthermore, under a fiber optic cable each device for spatial limited guided Forwarding an optical signal understood, in particular assembled Fiber optic cables and so-called "Wafe guides".
  • For a high bit rate optical data transmission between an optoelectronic transmitter and an optoelectronic transmitter receiver it is necessary that back reflections to optoelectronic transmitter a certain, set in standards Do not exceed the limit, for a trouble-free Ensure operation of the optoelectronic transmitter.
  • In a known coupling arrangement, the optical fiber contained at the end in a plug is in physical contact with the coupling element. The coupling element has on its side facing the optoelectronic element a surface region which reduces back reflections. Here, the coupling element is designed in the form of a light guide section whose axial extent is greater by a multiple than its diameter. The light guide section is contained in a connector. The coupling end face facing the end of the light guide section terminates at a first spherical end face of the connector, while the optoelectronic element facing the end of the light guide section terminates at a second provided with a beveled end face of the connector. The coupling housing has a housing block receiving the optoelectronic element, to which a plug-in sleeve for holding the plug and the connector is fastened. This socket is formed axially comparatively long to ensure a secure fit of both the plug and the connector ( US 5,937,122 ).
  • Starting from an optical coupling arrangement having the features of the preamble of claim 1 ( US 5,937,122 ), the invention has for its object to make the coupling housing shorter and easier.
  • According to the invention This object is achieved in a first variant in that the coupling element lens-like and as an integral part of the coupling housing is formed, and that the coupling element at its the optoelectronic element facing side a bevel cut having.
  • In A second variant of the invention provides that the coupling element is designed as a plane-parallel plate, at its the optoelectronic Element facing side a reflection-reducing coating and is supported directly in the coupling housing.
  • One The essential advantage of the new coupling arrangement is that that the axial extent of the lens-like coupling element same in size or even smaller than its diameter necessary for optical coupling is. This makes it possible the coupling arrangement to make a total of axially shorter.
  • There formed the coupling element as an integral part of the housing is, for example, the coupling element in one piece with the coupling housing in a common injection molding getting produced.
  • The Forming the coupling element as a plane-parallel plate allows a especially short design.
  • The embodiments of the invention are in the 1 and 2 the drawing shown.
  • there demonstrate
  • 1 a sectional view of a coupling arrangement, with a lens-like coupling element with an oblique cut on its side facing the optoelectronic element side
  • 2 a sectional view of a Kopp Arrangement with a plane-parallel plate.
  • The embodiments of the coupling arrangement according to the 1 and 2 have an integrally formed coupling housing 1 with a first cylindrical receiving area 2 , for receiving a light guide plug 3 and a second cylindrical receiving area 4 for receiving an optoelectronic element 5 on. The light conductor plug 3 contains an end 6 a single-mode optical fiber 7 which has a core diameter of about 5 to 9 microns.
  • According to the 1 is the coupling element 12 as a lens with the coupling housing 1 formed in one piece from an optically transparent material. The lens can according to 3 a biconvex lens or according to 4 be a planon vlexlinse. The lens has a surface area designed as an oblique cut 16 on top of the optoelectronic element 5 is facing.
  • According to 2 is as a coupling element 12 a plane-parallel plate provided on the the optoelectronic element 5 facing side a reflection-reducing coating 20 having. The reflection-reducing coating 20 dampens the return reflection of incident light rays. The plane-parallel plate is from the first receiving area 2 out into the window-like recess 11 inserted as a stop for the plane-parallel plate in the direction of the optoelectronic element 5 a step-shaped narrowing 14 having.
